BlockLayerTypeEnum

BlockLayerTypeEnum in the ABBYY FineReader Engine API — Layers (background, foreground, etc.) to which page blocks belong; supports overlaid blocks.

BlockLayerTypeEnum enumeration constants are used to describe the layers to which blocks belong. Blocks may be overlaid, for example, a text block may lay over a background picture block.

typedef enum {
 BLT_Background,
 BLT_Foreground,
 BLT_Hidden
} BlockLayerTypeEnum;
